    决定教育成败的关键法则:教育中的二八定律

    决定教育成败的关键法则:教育中的二八定律


    来源:学习力教育中心  作者:余建祥

      在教育中,有一个让人无法理解的现象:学霸们的父母都很轻松,在孩子身上投入的精力并不多,但孩子却表现优异;而很多父母在孩子身上倾注了大量的时间、精力和财富,但孩子却表现平平,不尽如人意。一边是低投入高产出,另一边却是高投入低产出,形成了鲜明的对比。到底是什么原因造成了如此反差巨大的现实呢?

      一、普遍存在于社会学、经济学中的二八定律

      有一个著名的定律,揭示了这一现象背后的本质。二八定律是19世纪末20世纪初意大利经济学家帕累托发现的。他认为,在任何一组东西中,最重要的只占其中一小部分,约20%,却对结果会产生80%的决定性作用,其余80%尽管是多数,却是次要的,因此又称二八定律。

      1897年,意大利经济学者巴莱多偶然注意到19世纪英国人的财富和收益模式。在调查取样中,发现大部分的财富流向了少数人手里。同时,他还从早期的资料中发现,在其他的国家,都发现有这种微妙关系一再出现,而且在数学上呈现出一种稳定的关系。于是,帕累托从大量具体的事实中发现:社会上20%的人占有80%的社会财富,即:财富在人口中的分配是不平衡的。同时,人们还发现生活中存在许多不平衡的现象。因此,二八定律成了这种不平等关系的简称,不管结果是不是恰好为80%和20%(从统计学上来说,精确的80%和20%出现的概率很小)。习惯上,二八定律讨论的是顶端的20%,而非底部的80%。人们所采用的二八定律,是一种量化的实证法,用以计量投入和产出之间可能存在的关系。

      通过二八定律(二八法则),延伸出很多著名的法则,如:

      贵宾法则。给一个公司带来80%利润的是20%的客户。按照这个原则,如果能把这20%的客户找出来,提供更好的服务,对于公司的发展和业绩的增长无疑是最大的帮助。

      品牌法则。20%的强势品牌,占有80%的市场份额。一般来说,第一品牌的市场占有率比第二品牌高出一倍以上,在行业中是价值最大的品牌。在网络界,三大门户网站无论是在吸引力方面,还是收入方面都占据网络产业的绝大部分。

      通过二八定律也延伸出很多现象,如:

      管理学:通常一个企业80%的利润来自它20%的项目。

      心理学:20%的人身上集中了人类80%的智慧,他们一出生就鹤立鸡群。

      大智出有大伪,朴素的力量同样托起了蓝天。总而言之,在原因和结果、投入和产出、努力和报酬之间存在的这种不平衡关系,可以分为两种不同类型:多数,它们只能造成少许的影响;少数,它们造成主要的、重大的影响。

      80/20法则不仅在经济学、管理学领域应用广泛,它对我们的自身发展也有重要的现实意义:学会避免将时间和精力花费在琐事上,要学会抓主要矛盾。一个人的时间和精力都是非常有限的,要想真正“做好每一件事情”几乎是不可能的,要学会合理地分配时间和精力。要想面面俱到还不如重点突破。把80%的资源花在能出关键效益的20%的方面,这20%的方面又能带动其余80%的发展。
